TAILORS CRAYON-SHARPENER'.

TO ALL PERSONS TO WI-IOM THESE PRESENTS MAY COME:

' Be it known that we, BENJAMIN lW. MINOR and ALLEN CoLBUnN, of Boston,in the county of Suffolk, and State of Massachusetts, have invented a'new and useful Tailors Crayon or Chalk-Sharpener; and do hereby declarethe same to he fully described in the following specification, andrepresented in the accompanying drawings, of which- Figure 1 is a topview.

Figure 2 is a sido elevation.

Figure 3, a longitudinal section; and

Figure 4 is a transverse section of'it.

This invention answers not only as a weight to hold the cloth or patternin place, and a means of sharpening a piece of crayon, but as a devicefor intercepting dust or waste cut from the crayon, and preventing itfrom getting upon the floor, bench, or dress of an operative- In thedrawings, A denotes a flat and heavy base or weight, surmounted by acup, C, the latter serving as a handle to the weight, by which it may beraised as occasion may require.` AAcross the cup the cutter or cuttersare arranged, the same consisting of-a tube, a, and a thin blade o-rbar, b, heated and braz'ed together, the blade being extendeddiametrieally across the tube and projected in opposite direction fromit. The bar and the tube have V-shaped notches made in them, as-shown atefy, each serving as a means of reducing the crayon plate of chalk to asharp edge, the chips or powder being caught by and in the cup. Theweight, besides answering the purpose above mentioned, serves to keepthe 'sharpening-knives steady during the process of sharpening thecrayon, the form of which is given in side view in Figure 5, and in endview in Figure 6. The 'niode of making "the cutter is advantageous, itbeing better than a single blade, as it serves to4 steady the crayonWhile in the act of being cut, and causes itto be cut with a straightedge.

Heretofore, in sharpening a cra-yon, it has been customary for thetailor to accomplish it with or by means of a penknife, and by scrapingor cutting it down on its opposite sides. This process causes the dustor shavingsl to gather upon his fingers or clothes or adjacent articles,much to hisinconvenience; but with our invention he has only to draw thecrayon through the notches of the cutter, the dust removed being caught-in the cup. By our invention a crayon can be much more expeditiouslyand better sharpened than by av penknife used in the common andwell-known manner. v

We claim, as our invention, the cutter, as composed of the cross-har andtube, arranged and slotted as described.

We also claim the combination and arrangement di' the cutter and thewaste intcrcepting-cnp.

We also claim the combination and arrangement of the cutter, the'wasteintercepting-cup, and the base or Weight, the whole being as and for thepurposes described.

ALLEN COLBJURN.
